Claims.

This invention relates to a sanding machine or a machine constructed andiarranged to emciently spread sand, salt or ashes or other material on -icy roads, sidewalks or pavements. With modern 5 tramc it is necessary to so distribute sand or other material when the streets or pavements are slippery and it is desirable to have some machine which will perform this operation quickly and emciently.

It is an object of this invention therefore, to provide a very simple and eillcient distributing device preferably carried on a vehicle which will distribute the material as desired over a certain area.

It is another object of the invention to provide such a distributing device comprising an elongated receptacle provided with agitating and discharging means', which discharge means may be adjusted as to the rate of discharge and it may have certain parts thereof rendered inoperative.

It is a further object of the invention to provide a simple and eillcient discharging device which as stated'. may be mounted upon a vehi-l cle and which may be readily placed in or outof operation or adjusted as to the rate of discharge by the driver of said vehicle and from a point adjacent his driving position.

These and other objects and advantages of the invention will be fully set forth in the following description made inconnection with the accompanying drawings in which like reference characters refer to similar parts throughout the' several views and in which- Flg. 1 is a view in side elevation of a vehicle such as a truck.showing the device mounted thereon;

Fig. 6 is a vertical section taken on line 6-8 of Fig. 5 as indicated by the arrows.

Referring to the drawings a device is shown comprising an elongated box or receptacle A which has a rectangular upper portion andf has sides sloping toward its center with just enough inclination to have material move downwardly by gravity. The receptacle A is constructed and ar`\ ranged to be-mounted upon a vehicle B. Suchv vehicle may be of any suitable "construction, preferably of the truck type and such a vehicle is shown in Fig. 1 of which it will only be necessary to consider the frame members Bi, the wheels B2 and the driver's cab B3 having the driver's seat B4 therein. This receptacle comprises end 5 plates or frames it and 6. Plates 4 and 5 are mounted upon frame members BI. A side plate t extends between plates 4 and 5 and is bolted or connected thereto at its ends in any usual or suitablemanner. Plate extends from adjacent one upper corner of the end plates or frames downwardly to substantially the central bottom part of said end plates or frames. Another plate 1 extends between end plates 4 and d and is likewise connected thereto in any usual or suitable manner. Plate 'l also extends from adjacent one upper corner of the end plates 4 and 5 namely, the corner opposite that to which plate 6 extends, and plate l extends downwardly at an angle toward the lower end of plate 6. Plate l, however, has its lower edge' spaced some distance from the lower end of plate 6 and has secured thereto and extending longitudinally along its outer side and adjacent its lower edge a bar or narrow plate 8. Another plate 9 is provided which'is hinged to plate 8 and thus to plate l by a plurality of hinges I0 which will be secured to plates 8 and 8. Plate 9 is arranged to be against plate I and extends downwardly toward the lower end of plate 6 and is disposed so that its lower end will engage the lower edge of plate B as shown in Fig. 3. A member I3 is secured to the outer side of plate 9 somewhat adjacent the lower edge thereof-having formed therein a socket of general spherical form. A rod i2 has a ball at the end thereof received i'n the socket in member i3. Rod i2 passes through a. block Il and is provided with threads for some distance engaging threads in said block, Block Ii is swinglngly mounted in. a bracket ila securedy to a plate 4a fastened to the outer end of its threaded portion comprising 'fork'members l2b and i2c and having a block i2d disposed between the forks thereof and respectively connected to said fork members by the pins i2e.' Rod i2 has a portion I2a extending from fork member I2b to a point adjacent the driver's seat B4 and which has a hand wheel 2l at its end. It will be seen that by turningf the wheel 21 plate 9 can be moved toward or from plate 6. Block il is swinglngly mounted to prevent binding due to the fact that member I3 swings in an arc. A bar or plate i4 extends between and is secured to the end plates 4 and 5, the same being disposed adjacent the lower end of plate 6 at the 55 ,outer side thereof. A plurality of plates or slide members I'are provided, the same extendingv throughout the length of plate 6, resting on member I4 and having their adjacent sides in contact, which sides extend at right angles to the lower edge of plate 6. Plate I4 has secured therein headed and nutted bolts I 'l which project through slots I5a in plates I5, which slots are of considerable length and extend parallel to the sides of said plates. Springs I6 are secured at one end to the bolts Il and at their other ends to plates I5 at the outer ends of the slots I5a. therein. Bolts I'I are equipped with washers |10. below member I4 and above plates I5 respectively and with nuts I'Ib. The plate 6 has its lower edge disposed substantially horizontally and the plates I5 are disposed so that they will move under this lower edge substantially in contact therewith. Springs I6 are under considerable tension and tend to move the plates I5 inwardly against lthe lower edge of plate 9. Spring I6 are disposed for themost part within the slots I5a. Bolts I'I act as guides for the plates I5 as they move inwardly and the washers on bolts I'I are of a size to span the slots I5a. and be clamped down on top of plates I5 so as to hold the same stationary and prevent movement thereof by the springs I6.

The end plates 4 and 5 have secured thereto bearings or bearing boxes I8 in which is journalled a shaft I9 which extends lengthwise from plate 4 to plate 5 and between plates 6 and 9 and is thus disposed in the bottom of the receptacle formed by plates 4, 5, 6, 'I and 9. Shaft `I8 has projecting therefrom throughout its length and in circumferentially spaced relation pins I9a shown as of conical or pointed formation. Shaft I8 has rotatably mounted in the outer end thereof a pulley or sprocket 2I which will be arranged to be driven by a suitable belt or chain 22 from power furnished by a part of the vehicle on which the device is mounted. Chain 22 may run over a sprocket B5 secured to a wheel of said vehicle. A clutch member 20 is also provided, the same being shown as having the two parts 20a` and 2Gb and this clutch will be arranged to connect shaft I8 within the said receptacle to the sprocket 2|. One part 20a of this clutch is secured to the side of sprocket 2I and has spaced laterally projecting teeth while the other part 20h is nonrotatably but slidably secured to the projecting and reduced portion of shaft I 9, the same having spaced laterally projecting teeth adapted to interengage with the teeth on part 20a. Suitable mechanism will be provided for operating clutch 28.

This may include a bell crank lever 23 pivotally connected to a bracket 28 by a headed pivot 29. Bracket 28 will be secured to the outer side of plate 4. Lever 23 has one arm 23a comprising a clutch fork embracing part 2Gb and disposed in a. central groove therein. A rod 24 is pivotally connected to the other arm of lever 23 and extends to adjacent the drivers position in the vehicle B. Rod 24 could be pivotally connected intermediate the ends of a hand lever 25 pivotally mounted at its lower end at 26 in said vehicle.

.With the described sti ucture the sand, ashes, salt or other material to be distributed will be placed in the receptacle formed by plates 4, 5, 6, 1 and 9, the space within which is designated as 30. When it is desired to discharge the material the driver o1' operator will turn wheel 21 and this will move rod I2 in the member I I and swing the lower end of plate 9 the desired distance away from the plate l5.l The driver will then push upon lever 25 to pull upon rod 24 and operate the clutch member 20 to connect shaft I9 to sprocket 2, so that shaft I9 is rotated. This shaft with the pins I9a thereon will agitate and stir the material within the receptacle and break up any lumps therein. Shaft I9 with the pins I9a may also act as a feeder but is not necessary when ne loose material is delivered. The material will be thus discharged in the desired amount as the vehicle moves along and will be discharged onto the roadway, street or pavement. It will sometimes be desired that the material benot fed throughout the full length of the receptacle or of plates 9 and 5. The nuts on the bolts I'I holding certain of the slides I5 will be loosened and this will permit the springs I6 to move the plates I5 against the lower end of plate 9, these slides moving under the plate 6. Each slide that is so permitted to move will thus partly close the discharge opening and prevent any discharge from the receptacle throughout the width of said plate. Thus the plates I5 throughout one end half of the receptacle could be loosened and the material discharged only through one-half of the length of plates 6 and 9. On the other hand, alternate plates IB might be made to move and the material would then be deposited in parallel streams or zones. The plates I5 will of course, move inward under the influence of springs I6 until they meet the edge of plate 9 no matter what distance it has been moved from plate 6. The plates I5 will be moved backward of course, should plate 9 be moved by operation of shaft I2.

From the above description it is seen that I have provided a simple and efl'lcient structure of distributing device and one which can be easily and quickly operated to discharge as desired by the driver of the vehicle on which the receptacle is mounted. If the material is fine and quite fluent it might not be necessary to operate the shaft I8. By use of the plates I5 as described, the material can be distributed in the desired zones or areas. The receptacle comprising members 4, 5, 6 and 9 is constructed to have a large carrying capacity. The structure is easily made from material which can be readily procured and can be made quite strong and rugged. It is obvious that, the structure will have a high degree of utility for`the purpose intended.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts,l without departing from the scope of applicants invention, which generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and dened in the appended claims.
